4.Heat Treatment of 42CrMo4 Steels
Annealing of 42CrMo4 Steels
- Warmth metal 42CrMo4 forged metal slowly and gradually and extensively to 800-850 degC
- Awesome little by little in the furnace to the temperature 480 deg
- Full annealing the steel in the air.
RFQ OF 42CRMO4 EPT
Quenched and Tempered (Q T)
- Warmth 42CrMo4 steel slowly to 880 degC
- Soak at this temperature then quench in oil
- Temper as soon as 42CrMo4 steel attain space temperature (20 degC)
- Warmth uniformly to the appropriate temperature of 560 degC
- Withdraw the 42CrMo4 substance from the furnace and awesome in the air.
